While going through the Unit 1 (HSN21000) notes i think ive spotted some mistakes. They are not major mistakes just mistyped no's and signs.
Ok first one is on Page 7, Under "Using simultaneous equations".
The 5th line down, after the addition of the two equations, shouldnt it read,
" 18y=2 ".
Next one is on Page 8, at the very bottom under "Composite Functions".
In example 1b) The 2nd line and after, shouldnt it read,
" f(g(x)) = f(x+1)
=3(x+1)
=3x+3
Can u plz chek these as it mite be me, my maths isnt that great!
Cheers.
